fo all retentit may concern:

Be it known' thet 1, Jol-1N Ur'ro riemen, Jr., e citizen oi the United States, residing at Lowell, in thecounty o1" Middlesex and State of Massachusetts, have invented cer-tain new o and .useful Improvements in Induction-Coils,

`proveniente in Vibrating ineel'ienisin for `interrupting .currents LVL spark coils, No. 825,830, end issued lo nie, Julyti), 1905. i accomplish this by prfwiding` en iron piete which contactsy e soit -ironirni mounted upon n 1oase oi -non-inegnetie ine: i,

through which projects en .eiectro-mognet beneath n. vibre: .Y wchenisni, and then in cerryingthe said iron i. tte down the eide of the sporti coihin order to eciiitcfie the. iioW of the niegfnetic eurrentthrough the meg netic circuit; that is, from one pole ofv the core, vthrough seid erin to the other pole of said core. i

Figure 1 is en elevation of my invention es applied to two ,unit .spark coils, the front of the cose heine; broken eway'to expose diegraniinotioelly the two coils, vibrating venes, soft iron` arms, and thin iron plates. Fig. 2 is e side viewin section online 2 2, in Fig. 1. Fig, 3 is it toopleii showing the two units or coils Stored in the cese; each soit iron erin` being,` in. nieteliio contectewithits respective thin iron plete. Fig Li is e. pien in section, on vline *i-fi Fig, sl'iowing' en empty cose, the two units shoe/nin i? having been removed., Whilei the thin iron pieter, ore left mounted in the cese,

i 'have shown'in the drewings'the heet inode now known to ine of embodying the principle olf' my invention.

A Wooden casing 1, having e cover 2,1715 provided. with :suiteble brecliete 3, supporting the seine, and, usuel, the prinmry end secondary terminals, and switch, and is mlopted Vtor the reception und reinoyei of, sty, two seperate coils or units 10, 10i, euch shown 7"u 1, 2 and 3.

.Forming the top oi each unit or coil` is e piece oi'insuiation 11i, 14', as herd rubber,

Each coil or unit vhes ne magnetic connection with the tion of my intention Will new hy erence to Fig. 1. The y nets or lines of force, indicated 'ted "nes, cnddue te the electric our rente created hy eny suitehie source lotrorrent and passing through the primary wind ing,"end Vibrating mechanism of the coil iioW from the pole of the core 18, 18', through the-Vibrating .vene 17, 117 the soft metal urine 15, 16, adjacent to the poieof the core, through the thin iron pietee 12,' 12', 13, 13, contacting the eeft metal erms, and then through ein oir space, to the opposite 'pole of the core, there thus being completed two magnetic circuits for each core, upon eachV .tectine'seid soit iron erin; the resuiting meg netiol heid is therefore stronger than heretofore used;v the Vibrating vene will operate quicker tien it otherwise would; and when used in connection with a sparking appera- 4 tus, es tor e geeolene engine, the' resulting I produced, will he 1n greater ahum dence than. will he Athe case when said pietee are dispensed. with.

.it is to he 'understood that while it is desirable to here each soft iron erin in inegteliiepiztte, yet itis to he understood that Sii lthe efficiency of a coil or unit is increased even only one arm is in magnetic'connection with a'plate in magnetic circuit leading Vto the opposite poleof the magnet.

Desiringto protect my invention in the brosrest manner legally possible,

. at i claim isz- 1."In a spark coil having an electro-magnet and one or more members of magnetic material, independent of the electromagnet,

and mounted adjacent to the core of theelec- Vtro-magnet; an iron mass which forms part of a magnetic .circuit upon the pole4 adjacent to said member, through said member, and through said iron-mass, tothe opposite pole 'of the core of the electro-magnet. 2. In a spark coil having an electro-magnet and one or more members of magnetic material independent ofthe electro-magnet, and mounted adjacent to the core' of the electro-magnet; an iron mass with which one of `lA4said members maybe moved' and held in iff-,magnetic Contact, and which forms part of a- '.ma netio circuit from the pole ad`acent to Y throng .said members may magnetic contact, yand which form part of `a "sai through said -iron'plate to the opposite polel ma neticjcircuit from the pole adjtacent to member, through said mem er, and

6.,In two or more spark coils, each of which has an electro-magnet, and one or more members of magnetic' material independent of its electro-magnet and adjacent to one pole thereof; two iron plates which are between any two ad'acent spark coils and which are magnetica y separated, but each of which is in magnetic contact with its respective member of magnetic material on its spark coil, and which forms part of the magnetic circuit from one pole of the electromagnet, through said member of m netic material, to the oppositepole of the sai elec,- tro-magnet.

7. In two or more spark coils, each of which has an electro-magnet, and two or more members of magnetic material independent of its electro-magnet and adjacent to one'pole thereof; two iron plates which are between any two ad'acent spark coils and which are magnetical separated, but each of.which is in magnetic contact with its respective member of magnetic material on its spark coil, and which forms part of the magnetic circuit from one pole of the electromagnet through said member of magnetic material to the opposite pole of said electromagnet andan iron plate. for veach other member of magnetic material, and forming a part vofthe magnetic circuit of-its respective electro-magnet. f,
